近年来,新型刀具不断涌现,切削加工条件已有所变化,本文针对一些具有代表性材料的切削加工,介绍一下有关刀具的选择问题。1、钢的切削目前市场上出售的刀具种类很多,其中用于钢切削的有陶瓷、金属陶瓷、涂复硬质合金、硬质合金和高速钢等。从加工方式来看,车削加工时,粗车主要用耐磨性和韧性均较好的涂复硬质合金刀具或P类硬质合金刀具;精车主要用耐磨性高、积屑瘤小的金属陶瓷刀具;在高速条件下进行稳定切削时,宜用陶瓷刀具;高速钢刀具主要用于切削速度不高的成形加工。
In recent years, new tools continue to emerge, cutting conditions have changed, this article for some representative materials, cutting, introduce the choice of the tool. 1, cutting steel Currently on the market for sale many types of knives, including steel for cutting a ceramic, cermet, coated carbide, carbide and high-speed steel. From the processing point of view, turning, roughing mainly wear resistance and toughness are better coated carbide cutting tools or P-type carbide cutting tools; fine car mainly with high wear resistance, Of the metal-ceramic tool; stable cutting under high-speed conditions, should use ceramic cutting tools; high-speed steel cutting tools are mainly used for low-speed forming.
